A quite common pain within the non-ASCII-World of Python on Windows
programming.
The quickest soliution I found is to switch the sys.setdefaultencoding to
UTF-8, follower on slot 2 is to switch default-encoding to latin-1.
Both solutions are productive in real world projects for 5 (utf-8) and 9
years (latin-1) with various apps by me; and a similiar solution is reported
by Chris Withers for running productive for 5 years.
Both solutions were called being highly dangerous by MvL and others on
c.p.dev; esp. pointing out problems that can happen concerning hashes /
dict-keys not comparing as expected.
A more work-intensive soluton: only use unicode inside your application and
have a dedicated encoding step when interfacing with the environment (the
MAL recommend way, find slides here:
http://www.egenix.com/library/presentations/#DesigningUnicodeAwareApplicationsInPython
)
one try in that step: make that string-substituion a unicode substitution.
(guessing that self.hostname is Unicode not String on winnt and up)
self.unique_name = os.path.join(dirname,
u"%s.%s%s" % (self.hostname,
tname,
self.pid))
(ATM converting my code step-by-step to that "only use unicode inside" way,
with having a sys.defaultencoding = "UTF-8" as "get less unicodexx errors
fallback")
